High Purity Graphite Screws Bolts Nuts


Custom Graphite Fasteners for Vacuum & High-Temperature Applications

Graphite screws, bolts, and nuts are precision-machined fastening components made from high-purity graphite materials. They are specifically designed for extreme high-temperature, vacuum, and inert gas environments, where conventional metal fasteners may deform, oxidize, or contaminate the process.

These graphite fasteners are widely used in vacuum furnaces, sintering furnaces, semiconductor equipment, and graphite hot zone assemblies, providing stable fastening performance under repeated thermal cycles.
